Answer 1

Option C

Explanation:

For the spinner,

Probability of spinning an even number =
`\frac{\text{Favorable outcomes}}{\text{Total outcomes}}`

Favorable outcomes = even numbers on the spinner

= 3

Total outcomes = Total numbers on the spinner

= 6

Probability of spinning an even number =
`(3)/(6)`

=
`(1)/(2)`

For the cube,

Total outcomes = total numbers on the dice = 6

Favorable outcome = Odd numbers on the dice = 3

Probability of rolling an odd number on rolling a cube =
`(3)/(6)` =
`(1)/(2)`

Probability of spinning an even number on spinner and an odd number on a cube =
`(1)/(2)* (1)/(2)`

=
`(1)/(4)`

Percentage probability =
`(1)/(4)* 100`

= 25%

Option C is the answer.
